Voice processor card diagnostics

Diagnosing VP card

faults

When you run voice processor card diagnostics, the system

loads the overlays on each node, and runs the voice processor

diagnostics for each VP card that is present in the node. The

system then initiates the voice-based diagnostics on each

channel.

Fault detection

The VP diagnostics check each of the digital signal

processors (DSPs) on the Voice Processor card under test.

If the diagnostics detect a problem on the card, then the

terminal prints a SEER, and the DSP with the problem

registers as faulty. If all DSPs on the card appear faulty, the

card will also register as faulty. Each DSP services two voice

channels, so the voice channel status screen will display two

faulty voice channels for each DSP fault.

When you start the node, the voice channels on a faulty DSP

are not brought into service. A faulty Voice Processor card

must pass out-of-service diagnostic tests before you can bring

it back into service.

The VP diagnostics issue class 53 SEERs. The SEER text

indicates the general nature of the problem. A description of

class 53 SEERs can be found in the Meridian Mail
